Active clinical trials for "Myopia"

The study is to clinically evaluate currently marketed contact lenses when used in an extended wear modality of up to seven days/six nights.

The purpose of this research is to determine if an investigational thin shield over the cornea can safely and effectively reduce or eliminate pain following Post Photorefractive Keratectomy (PRK). The thin shield is made of silicone. The materials used to make the corneal shield all have a history of use in medical devices, contact lenses, and/or corneal shields and have been used safely in the eye.

The purpose of this study is to determine whether less frequent dosing of atropine drops may be as effective as daily dosing for the treatment of progressive myopia.

In this study, ocular discomfort following intravitreal injection in naïve patients will be studied, as well as the efficacy of wetting agent (Optive eyewash) to prevent ocular discomfort.

This study is to evaluate the safety and efficacy of a new hydrogel daily disposable contact lens compared to the Bausch + Lomb SofLens® daily disposable contact lens when worn by current soft contact lens wearers on a daily disposable wear basis.

The purpose of this study was to assess and compare the effect of the repeated usage of 2 different care systems (one hydrogen peroxide based cleaning and disinfecting system and one PHMB containing multipurpose system) with ACUVUE® 2® and AIR OPTIX® AQUA contact lenses worn on a daily wear basis for a 3-month period.

The purpose of this long term safety study is to estimate the annualized endothelial cell loss (ECL) rate (for up to 10 years following date of implantation) of subjects previously implanted with the ACRYSOF CACHET Phakic Intraocular Lens (L-series) from precursor clinical studies C-02-23, C-02-40, C-03-21 and C-05-57.

To evaluate the effect of PEG-400 and Systane on quality of vision after LASIK.

To assess the one-month ocular effects of nightly application of experimental BHVI2 and 0.02% atropine eye drops either alone or in combination, in children aged between 6 to 13 years old with myopia and randomized to use of experimental BHVI2 eye drops, 0.02% atropine eye drops, experimental BHVI2 plus 0.02% atropine eye drops.

Monochromatic light creates longitudinal chromatic aberration, with short wavelength blue light forming a focal point in front of the retina and long wavelength red light forming a focal point behind the retina. The investigators hypothesize that such chromatic aberrations, induced by exposure to red or blue LED lights, will cause the choroid behind the retina to respond to bring the image into focus by modulating its thickness, either thickening in the case of blue light or thinning in the case of red light. The magnitude and direction of this response is difficult to predict as previous studies have shown opposite findings in non-human primates and rodents. Furthermore, the investigators hypothesize that exposure to red or blue light will induce changes in how the pupil responds to light, because the cells in the eye that are involved in pupil control are most sensitive to blue light.
